Difference between perfect square and a number that can be expressed as product of consecutive integers:

A perfect square is a number that can be expressed as the product of an integer by itself or as the second exponent of an integer¹. For example, 1, 4, 9, and 16 are perfect squares because they are the squares of 1, 2, 3, and 4 respectively. A perfect square can also be written as x^2, where x is an integer. A number that can be expressed as a product of consecutive integers is a number that can be obtained by multiplying two or more integers that follow each other in order. For example, 6, 24, and 120 are numbers that can be expressed as products of consecutive integers because they are equal to 2 x 3, 2 x 3 x 4, and 2 x 3 x 4 x 5 respectively. A number that can be expressed as a product of consecutive integers can also be written as x(x + 1)(x + 2)...(x + n), where x and n are integers. The difference between a perfect square and a number that can be expressed as a product of consecutive integers is that a perfect square has only one factor pair that consists of the same integer, whi...

What is a computer language

By Ali Khan -

 



Computer language :

A computer language is a way of telling a computer what to do. As we human understand different languages and communicate with one another similarly we also have to communicate with computer and tell  it to do some thing, so for this purpose we need a language that computer can understand because computer is not able to understand the general human languages we speak. 

 A computer language has a set of rules, words, symbols, and numbers that are used to write instructions for a computer. These instructions are called programs or software. The computer use these instruction and programs and perform the required task for the user. Different computer languages have different purposes and features.

Types of computer languages :

1: Low level language
2: High level language

Low level language:

 Low-level languages are closer to the way computers work, using binary numbers (0 and 1) or symbols (called mnemonics) to represent the basic operations of the computer.

Examples:
   Machine language is the most basic form of computer language, using only 0 and 1 to represent the instructions


High level language :

High-level languages are closer to the way humans think, using words and commands that are similar to natural languages like English.

Examples: 

Some examples of high-level languages are C, Java, Python, and SQL etc. High-level languages use words and commands to give an instruction to the computer that are more understandable and expressive for humans but these word and instruction are not understandable for the computer therefor compiler convert these instruction into binary language and then they are transfer to the computer.

C programing Lesson 1:

By Ali Khan -

Following are the few basic concept that must be understand before writing a program in C programing language. The C Character Set:                                             A character denotes any alphabet, digit or special symbol used to represent information. Variables And Constant:                   a variable is an entity that may change, whereas constant is an entity that does not change. In any C program we typically do lots of calculations. The results of these calculations are stored in computer’s memory. Like human memory, the computer’s memory also consists of millions of cells. The calculated values are stored in these memory cells. To make the retrieval and usage of these values easy, these memory cells ( also called memory locations ) are given names. Since the value stored in...

The Comprehensive Guide to CRT Monitors

By Ali Khan -

CRT Monitor Introduction: Cathode Ray Tube (CRT) monitors were once the epitome of display technology, dominating the market for several decades before the rise of LCD and LED monitors. While they have become somewhat obsolete in recent years, their historical significance and unique features make them a fascinating topic to explore. In this comprehensive guide, we'll delve into the details of CRT monitors, exploring their technology, advantages, disadvantages, and the reasons behind their eventual decline. Understanding CRT Technology: Basic Components: CRT monitors consist of a cathode-ray tube, which is a vacuum tube containing an electron gun and a phosphorescent screen. The electron gun emits a beam of electrons, and this beam is directed towards the screen, where it creates images by exciting phosphor dots. Color CRT Monitors: To display color, CRT monitors use a shadow mask or aperture grille, along with three electron guns—one for each primary color (red, green, and blue)....
